MATTRESS WITH TOILET ATTACHMENT Filed NOV. 17, 1949 Patented Oct. 27, 1953 UNITED STATES PATENT OFFICE 2,656,549 MATTRESS WITH TOILET ATTACHMENT John William Osbon, Jr., Dayton, Ohio Application November 17, 1949, Serial N 0. 127,968

11 Claims. (01. -91) This invention relates to an attachment for an invalid bed and more particularly to an attachment for the comfort of the occupant.

The invalid bed disclosed herein is similar to the invalid bed disclosed in my copending application for United States Letters Patent Serial No. 16,472, filed March 23, 1948.

An object of this invention is to provide an attachment for a bed, such that a vessel located below the top level of the mattress is accessible through an aperture in the mattress.

Another object of this invention is to provide a plurality of vessels nestled together and accessible from the top of the mattress through an aperture in such a manner that one or more of the vessels may be removed for emptying and sterilization as may be required.

Another object of this invention is to provide a vessel nested in an aperture in the mattress,

the top of the vessel being located below the top surface of the mattress, means being provided for covering the margin of the mattress, said means being provided with an annular flange projecting into the vessel so as to protect the mattress.

Other objects and advantages reside in the construction of parts, the combination thereof and the mode of operation, as will become more apparent from the following description.

Referring to the drawings,

Figure 1 is a perspective view of an invalid bed provided with an attachment.

Figure 2 is a cross sectional view taken substantially on the line 2-2 of Figure 1. Figure 2 is drawn to a larger scale than the other figures.

Figure 3 shows a view of the vessel and the parts associated therewith removed from the bed.

The invalid bed includes a bed portion l0 having the major portion supported upon wheels I2 through brackets I 4. One end of the bed is also supported upon caster wheels l6 through brackets 18. This permits the occupant of the bed to move the bed from place to place by manipulating the wheels l2, as more fully described in my copending application Serial No. 16,472. The bed portion In supports a mattress that may consist of sponge rubber or similar material. The mattress 26 is provided with an aperture registering with an aperture 22 in the bed portion ID. The aperture in the mattress is subtended by an annular shoulder 24. The shoulder 24 of the mattress supports an annular radially disposed flange 26 integral with areceptacle 28 projecting downwardly from the bed. The receptacle 28 provides a support for a telescopically disposed vessel or urinal 30. The vessel 39, adapted to receive and hold liquids, is

provided with a flared marginal portion 32 projecting above the receptacle 28.

For the purpose of sanitation and for the purpose of eliminating, foul odors, a strainer assembly has been used. ..-This strainer assembly includes a funnel member 40 having a cylindrical portion 42 terminating in a beaded portion 44 resting upon the fiared marginal portion 32 of the vessel 36. Member 40 is provided with a conical portion 45, terminating in a downwardly projecting tubularor annular flange portion 41. An elbow member 46, press fitted over the flange 51, projects downwardly from the underside of the conical portion 45 and is provided with an opening extending atright angles to the opening in the conical portion 45. Member 46 may be made from vulcanized rubber, or molded from plastic or made from; metal. A lid 48, pivotally mounted at 56, opens up whenever any liquid flows through elbow ,member 46 and automatically closes when they liquid ceases to flow, so as toprovide a valve for closing the opening.

, A strainer member that is provided with a solid cap 62 and a plurality of radially disposed openings 64 is seatedain the aperture in conical portion 45. order to prevent the accidental removal of strainer member 6|], a downwardly directed flange portion 66 is provided with a bayonet jointed slot 68, seated over a pin 16 fixedly mounted in position. Thus, it is impossible to removev member 66 without first releasing the bayonet-joint that is formed by the pin 10 in cooperation with the slot 68. The strainer member 60 isprovided with a rib 12 that limits the-downward movement of the strainer.

' In order to prevent solid matter from entering the vesse1 30; a filter member 80, which may be made from-filter paper, is loosely positioned in member 40, so as to permit only liquid to flow downwardly. into the vessel 30. Solid matter may be removed by merely removing the filter member 80.

' An annular ringmember or collar 84, made of rubber or any other'suitable resilient material,

overlies the top portion of the receptacle 28, the

vessel 30 and the margin of member 40. This ring member 84 is provided with an annular channel or recess 86, into which the upper portion of the vessel-30 and the upper portion of the strainer, assembly 40; project. one side of the channel forms an overhanging lip or annular flange 88, projecting downwardly into the cylindrical portion 42 of the strainer assembly. Ring member 84 is also provided with a radially disposed flange 9B overlying a margin of the mattress adjacent the aperture therein.

A rubber sheet I00, provided with an aperture and a downwardly directed flange portion I02, extends .over an adjacent portion of the mattress, so as to prevent the mattress from becoming soiled.

The assembly of the receptacle, the vessel and the parts associated therewith may be mounted in the mattress so as to be available for use :by the invalid at all times. If, for example, the patient or invalid is left alone foralongperiod of time, as when another :member or members of the family are at work during the day time, the patient or invalid may then wait upon "himself. After a deposit (if solid matter, the filter niember 89 *may be -r em'oved without removing the other-parts o'f the attachm ent.

"At intervals I it will be necessary to I remove the -vess'el 330, so. as to :empty it and sterilize it, "and at times itmay be desirable to remove the entire assembly. First, the-rubber sheet 100 is removes, 'then =the rubber ring member .84 is --rmoved. whereupon; member ill-and the parts associated therewith maybe removed: either with =-or without the vessel dfl. Finally, the receptacle 28 ir-lay be removed, if this is found necessary. Upon the rem'oval of member 4 9 and the 1 parts asso'ciate'd therewith from the vessel 30, strainer member sfl may -be r'emovedby releasing-the payenet joint, so as to permit the individual pa'rts to 'be 'cleahsed and sterilized. The re ceptaele 28 may -be reinserted; this followed by the wessevau bein'g'fpushe'd into place and then the strainer assembly together with i filter member fiil inay be m'ountedin po'sition. 'When these have iueen proi aei'l'y positioned, the rubberring memiben or collar d is inserted intoplace andflnally, the'rubber sheet is replaced.

H lde asseiiibly being located below the level e1. the top :of the mattress, the mattress being preferably made f-rom 'sponge rubber, it can readi'ly be seen that the parts may -=be left in place without "ilisciih rlioi'tto the patient or "invalid. ncrease-more, the assembly is sanitary "and at the-same time always ready foruse by -the "patient orinvalid -without the attention :or-an attendant.

The sheet; not shown,- ispreferably provided with an opening mounted in registry with 'the opening in member I 00. By thisarrangement thepatient is s'e'lf-suflicient for long periods of time.

Althoughthe preferred embodiment of the' device has been described, it willbe understood said vessel projecting above the annular flange of the receptacle and terminating below the top surface of the mattress, a strainer assembly mounted in the top of the vessel, and a rubber 5 collar having a radially disposed flange overlying the margin of the mattress surrounding the aperture, said collar having an annular channel in the bottom thereof, the upper margin of the vessel projecting into the channel, one side wall of thechannel forming an annulardip overhangingthe upper margin of the strainer assembly so as to protect the mattress from being soiled.
